Monthly summary for 2025-10: Focused on deprecating legacy ACTS package versions and expanding package availability and compatibility. Key efforts include deprecating ACTS versions (37.4.0 down to 0.08.0) by wrapping definitions with default_args(deprecated=True) and adding new package versions: vecmem 1.21.0, Rust 1.86.0 (with rust_bootstrap across OS/architectures), detray 0.104.0, and py-uv 0.7.5/0.7.15/0.7.22 with required Rust toolchains. These changes improve maintainability, enable future removal of deprecated versions, and broaden ecosystem support across platforms. No explicit bug fixes were recorded in this period; the work delivered strengthens business value by reducing legacy debt and expanding deployment coverage.

Month: 2025-09 - Package maintenance in spack/spack-packages focused on expanding GeoModel versions and deprecating legacy detray releases. Delivered two features improving version coverage and conforming to current dependencies, enabling users to access newer GeoModel functionality and migrate away from deprecated detray releases.

2025-08 – spack/spack-packages: Key features delivered include upgrading dependencies to align with current ecosystems and enhance rendering support. Specifically, Covfie upgraded to 0.15.x and Detray upgraded to 0.100.x, with a new dependency on actsvg >= 0.4.57 for Detray 0.100+ to enable newer rendering capabilities.

July 2025: Delivered targeted dependency updates to improve downstream compatibility and readiness. Updated Detray to 0.99.0 and ACTS algebra plugins to 0.28.0, with corresponding dependency constraint adjustments in the acts and detray packages to ensure downstream projects pull the latest fixes.

June 2025: Consolidated feature delivery and stability improvements in the spack/spack-packages repository, focusing on enabling the latest tooling while preserving CI reliability. The work delivered directly supports downstream projects by aligning package versions with current needs and reducing integration risk.

April 2025 Monthly Summary for andiwand/acts: Focus on developer experience and reliability of Spack-based ACTS workflows. Key outcomes include delivering installation troubleshooting documentation and improved guidance for running code with Spack-installed dependencies, addressing DD4hep factory discovery issues, and enabling faster onboarding for new contributors. While no major bug fixes were recorded this month, the documentation work reduces support overhead and accelerates integration of ACTS with Spack environments.

Monthly summary for 2025-03 focusing on CI stability and dependency upgrades for andiwand/acts to address build reliability and compatibility with newer toolchains.

February 2025: Delivered VecMem 1.14.0 release support across the Spack ecosystem, enabling installation and management of vecmem v1.14.0. Work spanned core Spack (spack/spack) and packaging configuration (spack/spack-packages). Key commits tied to the release were vecmem: add v1.14.0 (#49166) with hashes 29e3a28071e72396f5b5c223ea270a8e43cfe594 and 6b4ed247b732d93c6e5138354d804b6a2058dda1. No major bugs fixed this month; focus remained on feature delivery and cross-repo alignment to improve reproducible builds and user onboarding. This work strengthens dependency management, reduces install friction, and demonstrates robust packaging metadata, checksum verification, and release coordination across repositories.

January 2025 highlights for andiwand/acts focused on reliability, safety, and developer productivity. Key achievements include a critical Podio plugin bug fix and a broad build-system modernization that enhances cross-compiler reliability and reduces maintenance overhead. Podio Enum Fix: resolved enum conversion error by using toUnderlying for comparisons and tightened type checks using Eigen concepts for stronger compile-time safety. CI/Build Modernization: standardized third-party libraries as system dependencies via CMake SYSTEM flag in FetchContent, suppressed build warnings in standard workflows, and extended CI to support multiple compilers with a minimum CMake version of 3.25. These changes reduce build failures, streamline onboarding of new dependencies, and improve plugin integration reliability. Technologies demonstrated include CMake, FetchContent, system-dependency handling, multi-compiler CI, and Eigen concepts.

Concise monthly summary for 2024-12 for andiwand/acts. This period delivered key feature enhancements and reliability fixes that improve modeling capabilities, API ergonomics, and CI stability, enabling faster releases and more robust simulations.
